public class SimpleSAXParser extends Object
An XML parser that generates "simple" SAX-like events from a limited subset of XML documents. The SimpleSAXParser can parse simple XML documents; it doesn't support processing instructions or elements that contain both sub-element and character data; character data is only supported in the "leaves" of the XML element tree.Example:
Parsing the following XML:
<?xml version='1.0' encoding='UTF-8'?> <xml-doc> <foo a="1" b="2&3"/> <bar>Hello World!</bar> </xml-doc>
will result in the following method calls to the SimpleSAXListener:
startDocument() startTag("xml-doc", emptyMap, "") startTag("foo", a_b_Map, "") endTag("foo") startTag("bar", emptyMap, "Hello World!") endTag("bar") endTag("xml-doc") endDocument()

SimpleSAXParser
public SimpleSAXParser(XMLReader xmlReader)
Creates a new SimpleSAXParser that will use the supplied XMLReader for parsing the XML. One must set a SimpleSAXListener on this object before calling one of the parse() methods.- Parameters:
xmlReader- The XMLReader to use for parsing.- See Also:
setListener(org.eclipse.rdf4j.common.xml.SimpleSAXListener)
-
SimpleSAXParser
public SimpleSAXParser() throws SAXExceptionCreates a new SimpleSAXParser that will try to create a new XMLReader using info.aduna.xml.XMLReaderFactory for parsing the XML. One must set a SimpleSAXListener on this object before calling one of the parse() methods.- Throws:
SAXException- If the SimpleSAXParser was unable to create an XMLReader.- See Also:
setListener(org.eclipse.rdf4j.common.xml.SimpleSAXListener),XMLReader,XMLReaderFactory

Method Detail
-
setListener
public void setListener(SimpleSAXListener listener)
Sets the (new) listener that should receive any events from this parser. This listener will replace any previously set listener.- Parameters:
listener- The (new) listener for events from this parser.
-
getListener
public SimpleSAXListener getListener()
Gets the listener that currently will receive any events from this parser.- Returns:
- The listener for events from this parser.
-
getLocator
public Locator getLocator()
-
setPreserveWhitespace
public void setPreserveWhitespace(boolean preserveWhitespace)
Sets whether leading and trailing whitespace characters in text elements should be preserved. Such whitespace characters are discarded by default.
-
isPreserveWhitespace
public boolean isPreserveWhitespace()
Checks whether leading and trailing whitespace characters in text elements are preserved. Defaults to false.
-
parse
public void parse(File file) throws SAXException, IOException
Parses the content of the supplied File as XML.- Parameters:
file- The file containing the XML to parse.- Throws:
SAXExceptionIOException
-
parse
public void parse(InputStream in) throws SAXException, IOException
Parses the content of the supplied InputStream as XML.- Parameters:
in- An InputStream containing XML data.- Throws:
SAXExceptionIOException
-
parse
public void parse(Reader reader) throws SAXException, IOException
Parses the content of the supplied Reader as XML.- Parameters:
reader- A Reader containing XML data.- Throws:
SAXExceptionIOException
-
parse
public void parse(InputSource inputSource) throws SAXException, IOException
Parses the content of the supplied InputSource as XML.- Parameters:
inputSource- An InputSource containing XML data.- Throws:
SAXExceptionIOException
